Since then, many disease-causing microorganisms have been identified and means of controlling their harmful effects have been developed. In addition, means of channeling the activities of various microorganisms to benefit medicine, industry, and agriculture have been discovered. Molds, for example, produce [[antibiotic]]s, notably [[penicillin]]. See also [[bacteriology]], [[genetic engineering]].
